The right physical grade for the formulation you're making — Bordeaux mixture, foliar micronutrient feeds, and copper-based fungicide blends.
Spray formulations need a crystal that disperses evenly, not one that clumps in the tank or clogs nozzles.
Bordeaux mixture depends on a consistent, predictable reaction — inconsistent input copper sulphate means inconsistent mixture.
Fine crystal or powder grades dissolve fast enough for practical field mixing without excessive agitation.
Insolubles clog spray equipment and reduce the effective active content of the formulation.
Manufactured and graded specifically for spray-tank dissolution speed, not repurposed from bulk industrial stock.
Held to a tight insoluble-matter ceiling so your formulation performs the same, batch after batch.
Consistent copper content means consistent Bordeaux mixture strength without re-calibrating your recipe.
Phytosanitary certificates and COAs issued alongside every export shipment.
Copper input is verified before it enters the reaction stage.
Crystallisation and drying are sampled to track Cu% and moisture in real time.
Final batch is tested against agriculture-grade spec and issued a Certificate of Analysis.
Send your current specification or COA — we'll match it to a grade, or explain exactly where and why ours differs. Phytosanitary certification available for agricultural exports.
